In this way, others can intuitively know whether you have been vaccinated and how many shots you have taken. When the user vaccinates the first vaccine, Yuekang code will have a blue border and a blue lion head. After the second inoculation, as mentioned above, the middle of the health code will turn green, indicating normal.
At present, the frequency of checking health codes is very high. Be sure to open the Yuekang code before getting on the bus or taking the subway to enter the station, mainly to see if your code is green. Vaccination in the middle has little effect. No matter the yellow code or the red code, it is forbidden to enter the station, and now people are checking in and out of supermarkets and markets, which is very strict, mainly to reduce the risk of transmission, so we should actively cooperate with the inspection.
